WINDOW ATTACHMENT.

Specification of Letters Patent.

Patented Feb. 18, 1908.

Application filed September 24. 1907. Serial No. 394.324.

T 0 all whom it may concern:

Be it known that I, FRANK S. BURGESS, a citizen of the United States, and a resident of the city of New York, Mariner Harbor, borough of Richmond, county of Richmond, and State of New York, have invented a new and Improved Window Attachment, of which the following is a full, clear, and exact description.

This invention is an improvement in window attachments designed to prevent the rattle or vibration of the window sash.

It is well known that the sashes of windows in windy weather are continually shaking in the frame, causing much noise and consequent discomfort. I overcome this objection by my invention by providing a keeper having a spring and a bolt movable into the keeper against the stress of the spring; the spring preferably being movable from one side of the keeper to the other, whereby the same keeper may be used. at either side of the window.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a fragment of a window sash and the adjacent window frame with my improvement applied thereto and shown partly in section; Fig. 2 is a section substantially on the line 22 of Fig. 1,

looking in the direction of the arrow; Fig. 3 is a cross section on the line 3-8 of Fig. 1; Fig. 4 is a rear view of a face plate and bolt forming part of my improvement, and Fig. 5 is a face view of the keeper.

In carrying out my invention, I employ a face plate 1, having a depression 2, preferably rounded, in its front face, and. a flange 3 surrounding its upper edge. Seated in the depression 2 is a button 4 having a stem 5 journaled in an opening in the plate and constructed with an outer angular end 6, which is securely fixed in any suitable manner to one end of a bolt 7. The outer end of the bolt 7 is rounded off at both edges on its front face, as shown in Fig. 2, for a purpose hereinafter made apparent.

As shown in Fig. 4, the rear face of the block 1 is provided with a cut-out portion 8 in which the bolt 7 is seated, said cut-out portion leaving projecting lugs 9 and 10 at opposite ends, the lug 10 serving as a stop to limit the pivotal movement of the bolt 7 L in each direction, as indicated in dotted outline.

11 indicates a keeper, which consists of a long block having projecting flanges 12 at opposite ends, and a longitudinal slot 13, for the reception of the bolt 7. At each end and at each side of the slot 13, a slot 14 passes through the end of the keeper and acts to receive the ends of a flat, curved or bowed spring 15.

In the application of my improvement to the window, the plate 1 is applied to the frame of the sash at each side about midway of its length, the sash being cut out sufficiently to bring the flange 3 flush with the face of the frame. A slot is also cut into one edge of the sash, communicating withthe cut-out portion in its face, and is of sui'licient extent to admit of the bolt 7 being swung from a vertical to a horizontal posi tion, and vice versa.

After the plate 1 and bolt 7 have been applied to the sash, the keeper 11 is let into the window frame at a point where it will be centrally opposite the bolt 7 when the latter is swung to a horizontal position with the window closed, this application of the invention being illustrated in Figs. 1 and 3. IVith the attachment thus applied, on swinging the bolt down by revolving the button 4, it will be projected into the slot 13 of the keeper behind the spring 15, the latter acting to bind it against the opposite wall of the slot, as shown in Fig. 3. The bevel or cam edges of the bolt 7 above referred to adapts said bolt to easily enter the keeper behind the spring when swung on its pivot.

The attachment constructed as described need not be made in rights and lefts; but since both edges of the bolt 7 are bevel, this part of the construction may also be employed at each side of the window, as also the keeper 11, it only being necessary in the case of the keeper, to withdraw the spring 15 from the slots 14 at one side of the keeper and in sert the spring in the slots 14 at the opposite side.

It is obvious that the construction of the attachment may be considerably varied from that shown and described; and I consider that I am entitled to such modifications as fall within the scope of the annexed claims.

Having thus described my invention I claim as new and desireto secure by Letters Patent:

1. An attachment for windows comprising a bolt having a cam side face adjacent to its free end, a slotted keeper disconnected from the bolt, a spring carried by the keeper, and means for projecting said cam face of the bolt into the slot of the keeper behind and against the stress of the spring.

2. An attachment forwindows, comprising a pivoted bolt, a slotted keeper, a bowed spring having its opposite ends let into slots of the keeper, and means for projecting the bolt into the slot of the keeper behind and against the stress of the spring.

3. An attachment for windows, comprising a face plate, a bolt pivotally mounted at the rear side of the face plate, a keeper having a detachable spring, and means for projecting the bolt between the keeper and spring.

4. An attachment for windows, comprising a keeper having a longitudinalslot formed therein, slots passing at each side of the keeper through the ends thereof and communicating with said longitudinal slot, and a flat spring arranged in said longitudinal slot with the ends thereof passing into said communicating slots at one side of the keeper.

5. An attachment for windows, comprising a plate having a depression in the face thereof, a button seated in said depression having a stem j ournaled in said plate, a bolt rigidly fixed to said stem, a slotted keeper, a curved flat spring carried by the keeper and arranged in said slot and acting to bind the bolt against the keeper, and means for limiting the further movement of the bolt when in position in the keeper.

6. In an attachment for windows, a keeper having a longitudinal slot therein, and a bowed spring arranged longitudinally in said slot of the keeper and interchangeable from one side thereof to the other.

7. An attachment for windows, comprising a slotted keeper having a spring retained at its opposite ends therein, and a bolt movable into the slot of the keeper in the plane thereof and against the stress of the spring.

8. An attachment for Windows comprising a keeper having a bowed spring therein loosely retained at both ends, and a bolt movable into the keeper against the stress of the spring.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
